Document Summary
5. 3 lipids are a diverse group of hydrophobic molecules. Do not dissolve in polar solvents such as water. Dissolve in non polar solvents, like chloroform. 1 gram of fat contains 9 cal (1 gram of pure carbohydrate or pure protein contains only. Consist of: a glycerol= 3 carbon alcohol containing 3 -oh groups, one, two, three fatty acids. Phosphate group + other group = hydrophilic head. ** common in all living things on the planet ** Made of 3 rings with 6 c and one ring has 5 c. Steroids differ in side chains or functional groups attached. Ex: cholesterol: in animals; not found in plants. Precursor for synthesis of other steroids ex: sex hormones testosterone and estrogen. 50% of the dry mass of most cells. Are polymer and amino acids are the monomers. All have the same structure, an alpha carbon attached to.
